Overview

Interprets and displays messages received from TWELITE CUE.

Operation of TWELITE CUE

The factory default setting of TWELITE CUE is configured to CUE mode.

In CUE mode, it operates intermittently to enable coin cell battery operation, waking from sleep due to several factors and transmitting various data.

CUE mode is intended for operation verification of TWELITE CUE, activating all equipped sensors and LEDs.

Wake-up Factors

TWELITE CUE requires one of the following factors to wake from sleep:

Wake-up by timer (periodic wake-up)
Wake-up by acceleration detection
Wake-up by magnetic sensor (when a magnet is detected nearby)

Types of Data Transmitted

TWELITE CUE sends the following data in packets:

Detection events (see below)
Module power voltage
Magnetic sensor detection value
Acceleration data

Packet Attributes

The attributes of received packets provide basic information.

Attribute	Description
#????	The count of received packets so far.
Type	Packet type as the value of `E_PKT` in the `mwm5` library. Packets from TWELITE CUE are usually `PKT_PAL=02`.
ID	Logical ID of the sender, usually a value from `0..100`.
AD	Serial number of the sender.
LQ	Approximate reception strength (Link Quality Indicator).
SQ	Sequence number of the packet.

Events

In CUE mode, acceleration events are always output. Regardless of the wake-up factor, a fixed number of acceleration samples are measured after waking. Events are determined based on the acceleration measurement results.

Event	Number	Description
Dice	`1(0x00) .. 6(0x06)`	Determined based on periodic wake-up and magnetic sensor wake-up. If a large acceleration is detected after waking, an undetermined event (`0xFF`) may be detected.
Move	`16(0x10)`	Occurs when the acceleration sensor detects acceleration above a threshold, resulting in a move or shake event. Move occurs when the measured acceleration change is relatively small, (acceleration change detected but no continuous acceleration change).
Shake	`0x08`	Occurs when the acceleration sensor detects acceleration above a threshold, resulting in a move or shake event. Shake occurs when the measured acceleration change is relatively large, (continuous acceleration changes detected).

Quantitative definitions for acceleration thresholds and event detection conditions are not provided.

Voltage

Power supply voltage of the module [mV].

Magnet

Displays the detected magnetic pole or no detection.

There is no function to indicate whether wake-up was caused by magnetic sensor detection.

Acceleration

Displays acceleration measured after waking.

Samples: Displays the number of acceleration samples, fixed at 10 samples.
Rate ID: Sample rate of acceleration, fixed at 04 (100Hz).
X, Y, Z: Acceleration on three axes. Calculated as the average of 8 samples. Unit is milli-G (1000mG = 1G = 9.8m/s²).
